Ten hog marketing groups located in Kansas and Iowa were surveyed during 1993 to determine the success, operation, and management of hog marketing groups. Results offer insights into the structure and organization of cooperative hog marketing efforts. Several guidelines for organizing successful hog marketing groups are proposed. Producers interested in forming a marketing group should consider having a written agreement, hiring a marketing group coordinator, and marketing hogs on a carcass merit basis.; Swine Day, Manhattan, KS, November 17, 1994

Kansas Agricultural Experiment Station Research Reports
The problem of reduced reproductive performance in sows weaned at 5 to 11 days (early weaned) after farrowing was assessed by comparing estrous and embryonic traits in these sows and others weaned at 23 to 31 days postpartum. The effects of treatment of both groups of sows with PG600 and vitamin A also were studied. PG600 increased the number of sows in estrus regardless of weaning age and reduced the interval from weaning to estrus for early-weaned sows. Both vitamin A and PG600 tended to increase the number of embryos recovered at 11.5 days after the onset of estrus.; Swine …

Kansas Agricultural Experiment Station Research Reports
Data from two experiments were used to determine the feed cost per I of lean gain for high-lean growth gilts fed various digestible lysine levels (.54 to 1.04%). The cost for producing 1 lb of lean increased as live weight increased from 75 to 160 lb (Exp 1) and from 160 to 300 lb (Exp 2). However, in Exp I, the cost per lb of lean gain was minimized for gilts fed 1.04 and .94% digestible lysine (1.25 and 1.15% total lysine, respectively) from 75 to 90 lb and from 90 to 160 lb, respectively.

A total of 100 weanling pigs with an average initial body wt of 11.8 lb and average age of 17 d was used in a 38-d growth assay to determine the effect of castration on growth performance of nursery pigs. All pigs were fed the same Phase I, II, and III diets formulated to 1.6, 1.4, and 1.35% lysine, respectively. Data indicated no differences in growth performance between intact males and barrows in the first 38 d postweaning (12 to 48 lb).; Swine Day, Manhattan, KS, November 17, 1994
